Application led Hay 12, 1908. Serial No. 432,357.

To all 'whom it may concern.' 13e it known that I, GEORGE H. FoRsY'rH, acitizen of the United States, residing at Chicago, in the county of Cook and State of Illinols, have invented certain new and useful Improvements in Window Constructios' of which the following is a specification.

This invention relates to window constructlons,

certain features of the invention being applicable to windows of that class employ'n hollow sheet-metal sash members, an being applicable generally to sash members of any construction.

The general object of the invention is to produce an improved/'window wherein the sash should be automatically adjusted to snug engagement with the sashguides.

My invention will be readily understood when considered in connection with the accompanying drawings showing practical embodiments of the several features thereof, in' which,-

lJiigure 1 is a fragmentary elevation of a wi-tion of a sash and its guide, the latter nemg broken out to disclose features of the sash lock. Fig. 2 is a cross-sectional view on the line 2-2 of Fig. 1. spective elevation, with parts broken out, of one of the st-iles of the sash and. its coperating guide, more particularly illustrating the relative location and coperative action Vof the arts whereby a cushioning eifect combine with an automatic adjustment of the sash to a snug t in its guides is obtained. Fig. 4.- is a vertical sectional view in a plane at right anglles to the plane of the sash through the sas -stilel and its guide illustrating a somewhat sash-cushioning and adjusting device, this view showing also a spring-actuated cushioning device on the sill adapted to engage the lower margin of the sash. Fig. 5 is a fragmentary horizontal section on the line 5--5 of Fig. 4, looking downwardly Fig. 6 is a fragmentary vertical secti: on the line 6-6 of Fig. 5; Figs. 5 and 6 more particuerating means on the sill and ir the bottoms of the vertical sash guides for adjusting the sash automatically to a correct position and t in its guides.

' 'Referrin first to Figa-1, 2 and 3, 1 desigow sheet metalstile, 2 the lower hollow sheet metal bar, 3

other features of improvement construct-ion-v Fig. 3 is a per.

simpler form o 'f an intermediate' jecting three-sided tutes a housing and guide for a sash-cushloning and' adjusting mechanism hereinafter described.

The three sides of the housing for the cushioning and adjusting device above referred to are identified 1n Fig. 2 as 6, 6b and 6, for convenience in' the further description thereof. Slidably mounted in this housing and engaging the walls 6 and 6b thereof is an angle strip 7, which extends approximately the full height of the Guide, the lowervv end of said angle-strip t being slightly above the sill so as to permit said strip. to have a limited downward yielding movement permitted by cushioning devices supporting the same, ashereinafter described. Secured to and within this anglelstrip 7 near the upper and lower ends thereof are upperand lower cam-blocks 8 and 9, best shown in the perspective view Fig. 3. The upper surface of each of these cambloks is inclined or beveled in thev direction of a line bisectin the angle of the anglestrip thereby pro ucing a sloping triangular-saped surface 8 and 9 on the upper side of each of said blocks, each of these surfaces sloping downwardly from a pfnt coincidentwithrthe angle to a line connecting the o posite edges of the angle, the direction o slope thus being oblique to the plane of the sash. The lower cam-block 9 rests upon4 the upper end of a coiled. cornpressvion spring 10 (Fig. 3), the lower end of said spring resting uponl a ledge or bracket A1l secured to the wall 6c of the guide, and guided upon a central rod or stem 12 sliding through an aperture in the bracket 11 and carrying a stop-nut or-head 13 on its lower end. l-

Secured' to and embracing two sides of the stile 1 at points on the latter slightly above the relative locations of .the camblocksA 8 and 9 are upper andflower straps 14 and 15. Secured to or integral with that side of said straps which is adjacent to the three-sided housing of the guide are camblocks 16 and -17 designed to ccperate, respectively, wit the cam-blocks 8 and 9.

These'cam-bloclis 16 and 17 are shaped eX- ternally to a loosesliding t Within the angle-strip 7 and the Wall 6c of the housing1 and on their lower sidesphave oblique inclined or beveled vvsurfaces mating' and matching with the corresponding sur-faces 82L and 9a of the blocks 8 and 9.

By reason of this construction :it will be seen that the sash may be raisedV in its guides to a height at which the'I lower cam-block 17 carried by the sash engages the bottom of the upper cam-block .8 .carriedby the anglestrip, it being understood that theA normal distance between the cam-blocks 8 and 9 Will be ample to permit xthe maximum 'rei quired opening of the sash.--When theisash is closed, the cam-blocks 16 and 11T carried more particularly to Figs. 2, 5 and ti, 29 designates a stop located lin the bottom ot each of the main guide-grooves, which stop has its upper surface formed -on an incline 'whose Obliquity is both transversely of and in the plane of the sash. This surface is shown at 29, said surface having' a triangular form with its highest point or apex, designated a, located adjacent to the inner side ot the baseof the guide-groove, and its lowest edge, designated by lying` diagonally across the guide-groove, Each lower corner ot the sash is formed with a corrcspondingly shapcd cani incline' indicated at 30 in Fig. l. By reason of this construen tion it will be apparent that, when the sash inI its lowered or closed position, the

by the stile of the sash strike', with their neight of the sash resting` on the incline lower oblique surfaces, upon the upper oblique mating surfaces of the cani-blocks 8 and 9, with the double result that the shock of the fall of the sash is cushionedby the spring l0 (ot which there Will preferably be one oneither side of the sash) and the sash is automatically positioned; widthwise'A and at the same time" crowded toward the outer side wall of the saslrguide, thus producing a close fit with the latter and'oliiviating the 'necessity of the usual weather strips. t V

In Fig. 4 I illustrate a somewhat simpler form of mechanism designed to eifect-sulistantially the results above described avitlr out the use of the intermediate :nglevstrip 7. In this -orm of the tlevice,.upper and lower cam-blocks 18 and 19 are"yieldingly supported on coiled compression springs 2d and 2l restingon brackets 2Q, and Q3 secured directly to the Wall of the three-sided housing,r ot the guide, said cam-blocks being guided by stems Qllaand E25 passing through apertures in vthe brackets spectively.v Secured to the adjacent side of the stile 1 of the sash as by rivets QG are the cooperatingl cam members 27 and 28. The cooperating,l cani faces oi' these several cani members may be inclined either simply in a direction at right angles to the sash or in Van oblique direction to the plane of the sash,`

so as to aiutonuxtically adjust the sash either simply to a tight fit with the outer wall ot the guides when the sash is closed, orfto also automatically center the sashV in its guides, as describedy in connection with F l, Q and 3. f

In both vof .thoii'orms thus fardeseribed the springs l0 an'dzQO'and `.21 are the active agents not only in adjusting the sash, but` also Yin cushioninggthe sash on .its descent, preventing possible injury and breakage `in the event of a sudden fall of the sash. I also provide other meansfor cushioning and adjusting the sash vvhiehnnayA be used either inl association with the ydevices above de vscribed or independently thereof'. Referring :22 and Q3, re-` to crowd the sash both toward the or Wall ot' the guide and toward the vertiealcenter of tl e sash, thus both adjusting the sash lo a tight fit,'as nell as correctly positioning or centering it. The stop 2S) may have its upper surface inclined simply in a direction transverse to the plane oit' thesush instead oi: oblique thereto, and the said stop may also be springsupporled, ii". desired, so as to'produce a cushioningeli'ect.

,ln cooperation with the last described feature l also employ an'ieuns i'or eiliccting a snug closure at the lower margin ot 4the sash, this means as herein vshown consisting fot a wedneshapcd-strip or bar Bhhiist shown in. Figs-:1l and, 5, which is mounted upon the si'l be and is slidahleI ti'azisversoly or the plane o't the sash, being normally urged towardlhe sash by a series ot coiled compression sp1-inns B3, which latter, togel her with the wedge strip 3l', are prehiralily s-:lidalily mounted in a hollow sill cap fl. The upper edge of the wedge strip Sl'has an in! clination correspondingjand ,'Jnatchinjl :with that oi the lower 'edge oi the sash, so'"thal as the strip cron'dtul beneath the sash a very snug' and tightn tit is insured, thusjiireventing access ot' dust,fnioisture, cold air and vthe like at that point.. n

Y,l'hih, l have shown a4 pluralityY ol` eo operating; pairs off cam devices for adjusting,r the sash, one pair alone may be eni- `ployed within the purview ot the iniiention, since `by omitting* the lowcrof .the aliued Ipairs lli, 8 and I7, 9, thelimitation to the height to which lthe sash may be'raised is removed; It will also be observed that where the lower cam members ot each pairIl are independently supported, as in Fig. 4, or as in the ease of the members 8 or 9, and 2S), in Figs. l", 2 and-3, the bcneiit ot the rcombined action `rof both members may be secured even VWhere the Ltivo cam members of each pair mayv notjcome into contact and j action simultaneously',-"aswould not be the case Where any vtwo 'of the `lower cam menibers are rigidly ermnecteclA or `mounted on a 2h tends i l l l l i the forms and relative arrangements of the sash-guide having'a lateral extension, of a nosaeie common'rigid support, as, for instance7 the cam members 8 `and 9 of vFigsyl, 2 and 3. Furthermore, it will be evident that the cam-members carried by the sash, instead of those 'mountedr in the guide, might be spring-supported, if de,si1ed,tol stantially the same results.

It will be evident to those skilled in the art to which my imp ovementsl relate that, variations and modiircations in' respect to parts may be made without involving any departure from the principles invo1ved, or

' with said guide eiect sub-I 'b y and the other having a, slight cushioning v .substantially as described.
